Dependencies marked as optional aren't about spring-cloud-connectors

[ramnivas]

Not really. Try a project without one of these dependencies and use AbstractCloudConfig. You will find that it all works fine. In fact, the reason I added ServiceConnectionFactory as an intermediate object was to ensure that these optional dependencies remain so. Otherwise, cloud().dataSource() instead of current cloud().connectionFactory().dataSource() would have worked and preferred.

I did, and I got ClassNotFoundException all over the place that only went away when I added the dependencies in my deployment project when trying to classload AbstractCloudConfig.

I just pushed https://github.com/cloudfoundry-samples/spring-sendgrid (which does not have dependencies on anything but mail-related artifacts). It worked fine for me.

When you say you got CNFEs, do you mean as warnings or as errors. If it is the latter, can you share a small project that exhibits the issue?

[chrylis]

Exceptions, not warnings. Not sure whether this is the specific issue at hand, but the JVMS says that linking may be eager or lazy at the discretion of the implementor, and I was running on 1.8. A difference in link eagerness could produce the issue I'm seeing (CFNE on trying to load ServiceConnectorFactory, whose methods refer to the Spring Data factory classes).

I tried the same sendgrid app with https://github.com/spring-io/java-buildpack buildpack (uses openjdk 1.8.0_11) and it worked fine. Which version of JDK are you using? Can you try to push your app to CF using the https://github.com/spring-io/java-buildpack buildpack?

[chrylis]

I was running Oracle 1.8.0 (I think revision 5 at that point) locally, and I was getting the CNFE on a subclass of AbstractCloudConfig where the entire method body for the only method was return cloud.cloudConnector().mongoDbFactory();.

[ramnivas]

Still no luck. I tried with Oracle JDK, with https://github.com/cloudfoundry-samples/springmvc-hibernate-template, along with localconfig cloud connector. I didn't see any CFNE.

My JRE version info:

java version "1.8.0_11"
Java(TM) SE Runtime Environment (build 1.8.0_11-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)

Can you try with the latest version of either/both Oracle and openjdk?
